IMPROVEMENT iN FIRE-PLACE HEATERS.

Specilication forming part of Letters Patent No. 210,870, dated December17, 1878; application iiled March 8, 1878.

To all whom it may concern Beit known that I, ALONZO RICHARDSON MORGAN,a resident ot' Astoria, Kings county, and State Oi New York, haveinvented new and useful Improvements in Fire-Place Heaters, of which thefollowing is a specification:

This invention consists of improvements of the open-fire heater withexpanding combustion-chamber and jacket patented by iVm. L. Phillips,Januar Y 13, 1874, whereby the same is adapted for use in mantel-openings, and also whereby a very simple arrangement is obtained that enablesthe heater to be con- `,'eniently applied to ordinary lire-places, andaffords easy access for making the connectingjoint between the tire-boxand the expanding chamber, to make and keep it tight, and thus preventthe escape of gases ot combustion into the air warmed, and forming theatmosphere ofthe rooms warmed by it.

Figure l is a sectional elevation of the improved fire-place hea-ter anda lire-place in which it is arranged. Fig. 2 is a front elevation, andFig. 3 is a horizontal section, the latter being taken ou the line a aof Fig. 1.

Arepresents the open-fronted fire-box, which, in addition to theordinary combustion-space, has an expansion-extension, D, formed in thetop by the large backward projection of the back plate in the place ofthe usual pipe-connection, thereby considerably increasing thecombustion-space, and sensibly lessening the rapid escape ofthe heat andunconsumed gases. This extension D projects into the space behind thetire-box suiliciently to connect with the reverberatory chamber Elocated therein, taking the place of the ordinary smoke-pipeconnection., but being much more capacions at the junction at saidchamber, with which it makes the connection by entering a collar, H,projecting forward from its side, which `joint may be tted gas-tight,with or without cement. The reverberatory chamber E is located in thespace behind the lire-box, with its lower end a little below theextension D, so that its bottom can be reached readily through extensionD, for clcanin g out the soot and ashes readily which deposit therein.lt extends upward as high or higher than the mantel, as may be desired,while the lire-box is below the mantel, and projects forward from itmore or less. fit-hin chamberE is a deiiectingplate, I, to impede thetoo rapid es cape of the products of combustion, which said plateprojects down about as low as the bottom ofthe passage from thefire-box; but said passage and the plate are both wholly above the levelof the top of the front opening into the tire-box, the object of whichis not to impede the escape of the products of combustion to such extentas to cause, with ordinary chimney-draft, the regurgitation of gasesinto the room, which is a common complaint with ordinary tire-placeheaters when the doors are open. At the same time it is sought to makesuch hinderance to the escape as to -et- 'ect good combustion, and causethe air surrounding the heating-surfaces to be warmed as much aspossible.

The cham ber E is indepei'xdent and detachable from the tire-boxextension, enablin g each to be made and applied in different sizes,whereby each maybe adapted to the different areas or dimensions ot'chimneys already eX- isting or those that may be constructed speciallyfor these heaters.

The front plate, B, and the back plate, C, of the tire-box are projectedprominently forward, enabling theextension D to be formed directly overthe lire-box, with its back end not entendL ing beyond the back of thelower portion of the tire-box, so that, in cases where the tireplacealready constructed is so that the chamL ber E cannot be placed as highas desired without disturbing the arch F of the tire-place, it may bedropped lower down behind the lirebox, and have its collar H liXedhigher upon it, but generally the arch will not prevent the placing ofthe chamber E as high as desired.

The connection between the extension D of the nre-box and the chamber E,which is gen erally very diiiicult to keep tight, is, in thisconstruction, where access can always be had to it by removing the frontplate or mantelframe surrounding the heater. The situation of thereverberatory chamber E is such that its interior is completelyaccessible through the open fire-box and extension D, and may at anytime be cleaned from soot, which is not the case with other re-placeheaters.

The front plate, B, in which the front openin g ofthe fire-box is made,extends directly upward a short distance above the top of the iirebox,and thence backward at B toward the front Wall of the lire-place, andterminates in a flange, J, which extends over the top and down the sidesto the lire-place hearth, and serves, with the 'tlange K of the frame L,to securely connect the lire-box to the brick-work, the said frame beingfastened to the latter by any suitable device.

It will be seen that this construction affords a simple and easyT methodof setting up the theater by first enabling us to place the chamber Ewith its smoke-pipe attached in av perfectly secure position, and thento adjust perfectly the lire-box and its connection with the backchamber, and finally to place the frame L, which secures the tire-box.

The removal of the frame affords readyT access to the joint at H at anytime, should the ljoint require to be repaired, thus insurin g safetyagainst the escape of gases into the air, which is so common with otherheaters, yin which greater diiculty of attending to the joint exists.

The air for heating purposes enters through the opening in the hearth atO, and, after being heated, passes up in the chimney into the rooms tobe heated by passages of common arrangement. It may also enter throughregisters P in the front plate or in the base from the room containingthe heater', if desired, and in practice dampers Will be employed toturn it on or oft either l Having thus described my invention, what Iclaim, and desire to secure by Letters Patent, is-

l. The nre-box A, having a distinctivelyformed and capacious rearwardextension chamber, D, at the top, instead and in place of the ordinarypipe-connection, and the reverberatory chamber E, in combination, whensaid extension D terminates at andunites with said reverberatory chamberand said reverberatory chamber is located with its bottom accessiblethrough the extension D.

2. The combination of the open-fronted tirebox A, front plate B B',having flange J, and the frame L, having 'flange K, with a fire-place,substantially as described.

3. The combination of the open-fronted firebox A, havingexpansion-chamber D, front plate B B', having flange J, frame L, having`ange K, and the reverberatory chamber E, substantially as described.
